Googling "mixstock CRAN" I found the following:
Package 'mixstock' was removed from the CRAN repository.
Formerly available versions can be obtained from the archive.
Archived on 2014-08-30 as long-term memory-access errors were not corrected.
You might want to contact the maintainer of the package directly with your
questions.
